Calabi-Yau property for graded skew PBW extensions [PDF]
, 2017 Graded skew PBW extensions were defined by the first author as a generalization of graded iterated Ore extensions [36]. The purpose of this paper is to study the Artin-Schelter regularity and the (skew) Calabi-Yau condition for this kind of extensions ...

Skew PBW extensions over symmetric rings
, 2021 Our purpose in this paper is to characterize skew PBW extensions over several weak symmetric rings. As a consequence of our treatment, we extend results in the literature concerning the property of symmetry for commutative rings and skew polynomial rings.

Noncommutative coding theory and algebraic sets for skew PBW extensions [PDF]
, 2023 The classical commutative coding theory has been recently extended to noncommutative rings of polynomial type. There are many interesting works in coding theory over single Ore extensions.

Recent applications of chemometrics in one‐ and two‐dimensional chromatography
Journal of Separation Science, Volume 43, Issue 9-10, Page 1678-1727, May 2020., 2020 Abstract The proliferation of increasingly more sophisticated analytical separation systems, often incorporating increasingly more powerful detection techniques, such as high‐resolution mass spectrometry, causes an urgent need for highly efficient data‐analysis and optimization strategies.

The orbit method for Poisson orders
Proceedings of the London Mathematical Society, Volume 120, Issue 1, Page 65-94, January 2020., 2020 Abstract A version of Kirillov's orbit method states that the primitive spectrum of a generic quantisation A of a Poisson algebra Z should correspond bijectively to the symplectic leaves of Spec(Z). In this article, we consider a Poisson order A over a complex affine Poisson algebra Z.

European Journal of Sport Science, Volume 26, Issue 8, August 2026.ABSTRACT Sodium bicarbonate positively impacts performance, but its associated gastrointestinal symptoms (GIS) may limit use. This systematic review synthesized literature that has evaluated GIS with sodium bicarbonate supplementation. Literature searches were performed from February 2024‐March 2026.

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.ABSTRACT Natural history collections are unparalleled archives of global biodiversity, yet most specimens remain molecularly uncharacterised due to the technical challenges of historical DNA (hDNA), including degradation, low endogenous content and contamination.

Gelfand-kirillov dimension of skew pbw extensions [PDF]
, 2013 Gelfand-Kirillov dimension of Poincaré-Birkhoff-Witt (PBW for short) extensions was established by Matczuk ([15], Theorem A). Since PBW extensions are a particular example of skew PBWextensions (also called σ-PBW extensions), the aim of this paper is to ...
